Defragmentation for objects within object store

A non-transitory machine readable medium comprising instructions for performing a method, which when executed by a machine, causes the machine to:

• maintain an object, comprising a plurality of slots, within an object store, wherein each slot is used to store a unit of data accessible to applications hosted by remote computing devices, wherein the object comprises an object header used to store metadata for each slot;
• create a cloud block in-use map by walking a file system in a snapshot;
• evaluate the cloud block in-use map to identify a freed slot of unused data no longer referenced by the remote computing devices;
• determine that the object is a fragmented object comprising an in-use slot of in-use data and the freed slot;
• and
• compact the object to retain the in-use data and exclude the unused data as a rewritten object based upon a number of in-use slots being less than a threshold.

A computing device comprising:

• a memory comprising machine executable code for performing a method;
• and
• a processor coupled to the memory, the processor configured to execute the machine executable code to cause the processor to:
• maintain an object, comprising a plurality of slots, within an object store, wherein each slot is used to store a unit of data accessible to applications hosted by remote computing devices, wherein the object comprises an object header used to store metadata for each slot;
• create a cloud block in-use map by walking a file system in a snapshot;
• evaluate the cloud block in-use map to identify a freed slot of unused data no longer referenced by the remote computing devices;
• determine that the object is a fragmented object comprising an in-use slot of in-use data and the freed slot;
• and
• compact the object to retain the in-use data and exclude the unused data as a rewritten object based upon a number of in-use slots being less than a threshold.
